My son is graduating next month as well.  I am not planning on going since he is flying home to visit right after.  We talked yesterday and he is waiting to tell me what day he can fly home...we are hopeful it's the same day or next day.  His plan is to be home until he has to report to his next duty station.  He is looking for a reprieve from the humidity before he has to go back to in Virginia and NC.  I am not sure how to to the invite but I'd like to add you so I can ask about what to expect with Quantico.
